Hello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it. The grass is very thin and I was told that is because oak trees turn the soil acidic. I had lime put down last year but the grass still looks the same.ello all, I have a Scrub Oak tree in my front yard, and I have St. Augustine underneath it.

Acorns, which come from the Oak Tree can be very toxic to horses and ponies-especially when they are still green. Acorns contain tannic acid that can cause lesions in the intestinal lining with symptoms of weight loss and anorexia. Oak leaves also contain tannic acid and can be poisonous to a horse or pony.
